IMPRVEMENT" IN RAILWAY-RAIL CHAIRS.

Specification forming part o' Letters Patent No. 1&2,23, dated August26, 1873; application filed July 21, 1873.

To all Awhom it may concern:

Be it known that I, WILLIAM HUFFMAN, of Millgrove, in the county ofBlackford and State of Indiana, have invented a certain Improvement inRail-Chairs, of which the following is a specification:

The object of my invention is to' provide meansfor preventing therunning of the rails, as the longitudinal movement of the 4railsresulting from the traction of the rollingstock is technically termed.My improvement consists in the employment of a recessed lishthe ordinaryvertical flange B, formed so asto snugly fit the irregular surface ofthe rails D and E upon their exterior side. The top of the flange shouldbe made iiush with the top of the rails to afford additional support tothe tread of the wheels in passing over the junction of the rails, andto some extent prevent the brooming'of the` latter..` The ytop of thelan ge is curved downward at each end, which enables the wheels to runover it without bcing subjected to hammering shocks. Facing this flangeis a lip, C, which is formed upon the base of the chair, and hooks overthe base of the rails at their ends7 its length being about one-third ofthat of the chair. The lishplate F, which is of about the same length asthe chair, is recessed at f, and lits snugly over the lip C of the chairwhen applied, as clearly shown in Fig. l. rllhe chair and fish-plate aresecured to the rails by bolts G, in the usual manner, allowing for thecontraction and eX- pansion of the rails. The"base of the chair mayextend beyond the flange B, as shown in dotted lines in Fig. 2, so thatit may be spiked to the cross-tie upon both sides of the rails.

It will be observed that the tendency of the rails to slide endwiseunder the traction of the rolling-stock will be very effectuallycounteracted by the positive hold the rails have upon the lip C of thechair through the recessed tish-plate.

What I claim as my invention, and 4desire tov secure by Letters Patent,is

A rail-chair having a lip, C, in combination with a recessed iish-plate,F f, all applied to the rails inV the manner and for the purpose setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

VILLIAM HUFFMAN.
